Abstract

Installation for determining by pulsed neutronic irradiation the contents of the various constituents in a bulk material. Use is made of a measuring apparatus (1) including electronic irradiation source and the gamma radiation measuring region, means (2) which provide for the continuous circulation of said bulk material, means (6) for receiving data of resulting spectra and computing means (7) allowing to compare said data of the spectrum with the data resulting from the measurements carried out in similar conditions on each of the pure constituents whose presence is searched (4), as well as means (8) for reading the result of the averaged computation.
